reward

Mouri (Choshu) territory before the Battle of Sekigahara in 1600.
That was about Hiroshima Province, Shimane Province and Yamaguchi Province of now.
After this battle，it was became only Yamaguchi Prefecture.

De facto royal family of samurai at the time was Toyotomi clan.
(Toyotomi’s identification was not a samurai，was a aristocracy)

However，after the death of its founder ”Toyotomi Hideyoshi”，this regime headed to collapse rapidly.
Hideyoshi became king of Japan from farmers.
But his action of his late in life that apparently became "strange".
　
Domestic affairs and Foreign affairs，Its "strange" appeared to both.
He became a man who kills people quickly.
He did not kill the people as much as possible until became king.
Toyotomi had lost samurai's support rapidly and their support was gathered to Tokugawa Ieyasu.
　
Of course, the opposition was present.　
Representative five lords of Japan at the time were Toyotomi regime ministers.
Its top was Tokugawa and its No.2 was Mouri.　
　
Tokugawa was only ally of Hideyoshi's past lord.
Mouri was collaborator of when winning hegemony of Hideyoshi.　
　　
This power struggle bisected the Japan，war became inevitable finally.
　
・・・・・・・・・　
　
The commander of the Mouri army was lord's brother of before.
He had convinced Tokugawa victory of this power struggle.
Above all when Tokugawa was defeated (when their side was win).

"We can not keep the peace，Japan definitely falls back to the Warring States era.”
"Must create Tokugawa victory to make a peaceful world."
He was so convinced.
(Until then，war was followed by one hundred years in all around japan.)

"Conservation of the current status of the Mouri. "
On this condition he promised to betraying to Tokugawa side.
In fact，while being de facto Gen.，Mouri did not do combat against Tokugawa.
Eventually Tokugawa hegemony was established.

・・・・・・・・・

"I forgive you only.
I give you Choshu as reward.　
Other Mouri clan will be destroy."

Soon after，there was a notice from the Tokugawa so.

"It is breach of contract.
Before battle，Tokugawa had promised to preserve current status of Mouri."

He did protest so but it was in vain.

"Promise can be changed at our convenience any time.”
After this win,Tokugawa’s negotiations in japan became like that.

”I do not want the territory.
Please gives Choshu to the Head family of Mouri.”
Mouri escaped the destruction by his frantic negotiations.
